A fun one from Interactive Things that shows cover songs with a galaxy metaphor:
The panorama view shows the 50 top songs as individual planetary systems with the original work as the sun. Each planet represents a version of the song and it’s appearance indicates characteristics including genre, popularity, tempo, valence, energy, and speechiness. The radius of its orbit around the sun shows the years between the publication dates. This view allows you to compare the structure and density of the constellation of different songs from a high-level perspective.
